Textiles andacrylamide are closely related to each other. Acrylamide is a water-soluble organic polymer with excellent film-forming properties and adhesive properties. It can be applied to textiles to enhance their performance and improve their appearance. The use of acrylamide in textiles can also help reduce the use of harmful substances in textile processing, protect the environment, and reduce production costs. This review introduces the properties, types, polymerization methods of acrylamide, as well as their applications in textiles, including finishing, printing, dyeing and other fields. Finally, it summarizes the advantages and disadvantages of using acrylamide in textiles and points out the potential risks and opportunities in its application.
I. Introduction
Acrylamide is a water-soluble organic polymer with excellent film-forming properties and adhesive properties. It is usually prepared by polymerization of acrylic acid or its derivatives. Acrylic acid is an unsaturated carboxylic acid with a double bond between carbon atoms 2 and 3. Its chemical formula is C3H4O2. Acrylic acid can be polymerized to form polymers with different molecular weights and structures by adjusting polymerization conditions. These polymers have good water solubility, heat resistance, and mechanical properties. Therefore, they are widely used in textiles to enhance their performance and appearance.
II. Types of Acrylamide
There are many types of acrylamide, which can be divided into polyacrylamide (PAM), partially hydrolyzed polyacrylamide (HPAM), and carboxymethyl cellulose (CMC) according to their structure. These types of acrylamide have different properties and applications. For example, PAM is a non-ionic polyacrylamide with good water solubility and heat resistance. It is often used as a thickener, flocculant, or dispersant in textile printing and dyeing processes. HPAM is a partially hydrolyzed polyacrylamide with ionizable carboxyl groups on the side chain. It has better water solubility and ion exchange capacity than PAM. It is often used as a dispersant, flocculant, or binder in textile processing. CMC is a carboxymethyl cellulose derivative with good water solubility and film-forming properties. It is often used as a stabilizer, emulsifier, or protective colloid in textile processing.
III. Polymerization Methods of Acrylamide
The polymerization of acrylamide can be carried out by various methods, such as solution polymerization, emulsion polymerization, suspension polymerization, and inverse emulsion polymerization. These polymerization methods have different characteristics and are suitable for different applications. For example, solution polymerization is simple and easy to control, but it requires high-pressure equipment and high energy consumption. Emulsion polymerization can be carried out at low temperatures and pressures, but it requires complex emulsifier systems and poor heat resistance of products. Suspension polymerization can be carried out at high temperatures and pressures, but it requires high-speed stirring equipment and poor mechanical stability of products. Inverse emulsion polymerization can be carried out at low temperatures and pressures with good mechanical stability of products but requires complex oil phase systems with poor water solubility.
IV. Applications of Acrylamide in Textiles
Acrylamide has many applications in textiles, including finishing, printing, dyeing, and other fields. In finishing treatment, acrylamide can be used as a sizing agent to improve the surface properties of textiles. In printing treatment, acrylamide can be used as a thickener or flocculant to enhance the printing performance of textiles. In dyeing treatment, acrylamide can be used as a dyeing assistant to improve the dyeing performance of textiles. Other applications include using acrylamide as an anti-static agent, flame retardant, or antibacterial agent for textiles.
V. Advantages and Disadvantages of Using Acrylamide in Textiles
Using acrylamide in textiles has many advantages. It can enhance the performance and appearance of textiles by improving their water absorption, oil absorption, heat resistance, and mechanical properties. It can also help reduce the use of harmful substances in textile processing, protect the environment, and reduce production costs. However, using acrylamide in textiles also has some disadvantages. For example, acrylamide is a water-soluble polymer with poor oil resistance and heat stability under high temperatures. It also has certain toxicity and may cause allergic reactions in some people. Therefore, using acrylamide in textiles needs to be evaluated comprehensively based on specific applications and requirements.
